Collared Pratincole (Glareola pratincola) - HBW 3, p. 381

Taxonomy:Hirundo Pratincola Linnaeus, 1766, Austria. Forms superspecies with G. maldivarum and G. nordmanni, although range overlap with latter leads some authorities to exclude that species from the superspecies. Formerly considered to include G. maldivarum, and even on occasion G. nordmanni, as races. Has hybridized with G. nordmanni. Possible race boweni of W Africa included in fuelleborni; form “limbata”, described from Red Sea coasts, appears to be erroneous. Species has on occasion been regarded as monotypic. Three subspecies normally recognized.
